FOS

Abbreviation: FOS = Full of Shit

โ€ข It can mean that someone is lying, therefore full of shit.

โ€ข It can also mean the literal aspect, the state of being FOS.
(constipated) or (bowel obstruction)

That patient is totally FOS, just trying to get some drugs.

The patient in room 22 is literally FOS; constipated as hell.

They tried to tell me a BS story about losing their prescription, but I can tell they are FOS.

Typographical error of "go," it has now achieved near-meme status for certain internet users.

It originated on www.ar15.com on June 2, 2008. Popular and regular member "shaunofthedead" purported to have the opportunity of an orgy with some unknown people. After drunkenly deliberating for several hours whether or not he should take advantage of this opportunity, at 10:42:57 EST he posted simply "fuck it im foing."

He was never heard from again.

"fuck it im foing"
